Pump maintenance
Inspecting for leaks
The pump is equipped with a gasket system on the shaft to prevent adhesive
from leaking through it. On occasion, some adhesive may leak out, which
makes it necessary to retighten the screws or change the gasket.
Warning : Changing the gasket with a hot pump.
Release the shaft coupling from the pump. Retighten or remove the screws
that hold the gasket in place. Replace the gaskets and reassemble the parts.
Occasionally, as a result of the system’s heating-cooling cycles, it may be
necessary to retighten the screws.
Warning : Always wear protective gloves and goggles. Risk of burns.
Motor-gear maintenance
Cleaning the motor fan
Periodically inspect the condition of the motor fan and its vent screen.
If dust has accumulated, blow gently with air to clean it (remove the protective
cover, if necessary).
Checking the lubricant
The gear reducers are delivered filled with synthetic grease for lubrication
-free of outside contamination- ‘for life’. Ambient temperature 0 ÷ 40 °C, with
peaks of as low as -20 °C and up to +50 °C.
Use only those lubricants recommended by the manufacturer. The use of other
types may cause premature wear or damage to the gear reducer.
If the unit features a 0.375 kW gear motor, its gearbox will have a capacity for
approximately 0.19 kg of lubricating grease. In the case of 0.55 kW, 0.75 kW
and 1.1 kW gear motors, the gearboxes need at least 1.1 litres of lubricating
oil.
